Magpul® M-LOK® Index Stop™ – Ultra-Low Profile Half-Slot Hand Stop – Flat Dark Earth – MAG1568-FDE
The Magpul® M-LOK® Index Stop™ (MAG1568-FDE) is a premium, minimalist tactical control accessory engineered to increase support-hand placement consistency and maximize muzzle leverage. While traditional full-size vertical foregrips and wide angled hand-stops add excessive bulk, weight, and snag hazards to a sleek weapon profile, this micro-sized index hub masterfully shatters those mechanical drawbacks. Occupying an incredibly compact half-slot M-LOK footprint, it fits tightly onto aluminum forends without forcing weapon lights, laser designators, or top-rail tape switches to migrate out of their optimal forward mounting stations. It serves as an unyielding physical barricade that functions perfectly as a low-profile forward hand-stop or a rearward index block when executing a modern "C-clamp" thumb-over-bore support hold.
Molded in the United States from Magpul's legendary, proprietary high-strength polymer composite, this featherlight 0.4-ounce handling anchor is structurally built to absorb harsh operational concrete impacts, high barrel temperatures, and severe chemical exposure without fracturing. The defining technical edge of the MAG1568-FDE architecture is its highly versatile, **reversible texturing profile**. The face of the stop features an aggressive, slip-free horizontal ribbing matrix that naturally captures the user's index or pinky finger, providing an unyielding friction lock that grows progressively more secure when exposed to rain, mud, or hand sweat. Complete with premium, direct-mount **4140 chromoly steel hardware** treated in a mil-spec manganese phosphate finish, this ambidextrous upgrade ensures a completely locked-in grip profile across patrol carbines, competitive multi-gun setups, and custom low-profile builds.
Includes: (1) Magpul M-LOK Index Stop Handguard Accessory (Flat Dark Earth), Premium 4140 Chromoly Steel M-LOK T-Nut, and High-Tensile Torx Installation Screw.
*Handguard Geometry Note: This accessory is engineered EXCLUSIVELY to interface with standard octagonal aluminum M-LOK handguards and forends. It is NOT compatible with polymer M-LOK handguards or polymer forends, as the grip's specialized base contour requires the distinct flat angles of a standard octagonal metallic handguard to lock perfectly flush.
Key Features
- Active Weapon Counter-Leverage: Elevates control mechanics by giving the support hand a rigid micro-ledge to exert direct rearward tracking pressure, significantly smoothing target recovery.
- Aggressive Ribbed Seating Face: Features deeply molded horizontal structural ridges to keep fingers firmly seated, preventing hand slippage under intense rapid-fire cycles.
- Ultra-Compact Half-Slot Footprint: Efficiently earns its place by taking up only a half-slot of M-LOK rail space, preventing handguard clutter and preserving room for modern tactical electronics.
- True Ambidextrous Geometry: Uniform, symmetrical structural layout functions identically for either left or right-handed shooters without modifications.
- 4140 Chromoly Steel Hardware: Furnished with a high-tensile, heat-treated steel T-nut and fastener coated in an anti-corrosive manganese phosphate finish for a rock-solid lockup.
- Magpul Proprietary Polymer: Rugged, combat-tested structural composite shell resists harsh workspace friction, high barrel temps, and deep field scratches.
